Super Stocks Springs have i reached the limit?
The snubber was to control axle wrap-up where the pinion tried to climb up the ring gear tipping the whole pinion upward. The snubber would limit the amount of axle wrap-up effectively reducing/limiting the leafs from looking like a letter 'S'. But as noted, if you have springs that provide for body/axle separation, the snubber is really just a paperweight on top of the center chunk.
